Question

Answer 1

a) 

x = 5/6- 4/7

x = 11/42

b)

x= 7/9: 2/3

x = 7/6

Answer 2

a)

x + 4/7 = 5/6

x          = 5/6 - 4/7

x          = 11/12

b)

7/9 : x = 2/3

x          = 7/9 : 2/3

x           = 7/6

Answer 3

a) \(x=\dfrac{5}{6}-\dfrac{4}{7}\)

   \(x=\dfrac{11}{42}\)

b) \(x=\dfrac{7}{9}\div\dfrac{2}{3}\)

   \(x=\dfrac{7}{6}\)

Answer 4

A) \(\dfrac{11}{42}\)

B) \(\dfrac{7}{6}\)

Answer 5

a.  x + 4/7 =5/6

      x= 5/6 - 4/7

      x = 11/42

b. 7/8 : x = 2/3

x  = 7/9 ÷ 2/3

x = 7/6
